Scalable and Customizable Single‐Atom Coatings for pH‐Universal H2O2 Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
A universal one‐step soot‐deposition route was developed to convert various metal‐containing paraffins into conformal single‐atom catalyst (SAC) coatings on diverse electrodes, yielding robust, efficient SAC‐coated gas diffusion electrodes for H2O2 electrosynthesis.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

open access: yesAdvanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

O2‐Accessible Fe–N4 Active Site Density Boosts Efficient Oxygen Reduction to Fuel‐Cell Level

open access: yesAdvanced Materials, EarlyView.
This study investigates the role of hierarchical nanostructure design in optimizing oxygen mass transport for the oxygen reduction. Using atomically dispersed Fe–N–C catalysts with solid, yolk‐shell, and hollow structures, it demonstrates that the yolk‐shell architecture provides superior O2 accessibility to active Fe–N4 sites.
